Now the first thing you have to understand, is that this tutorial has to do with body wounds. So if you get naughtiest when seeing a cut, you probably will not want to continue on with this tutorial, because these wounds, if done well enough, will look pretty realistic, as the ones that I have made below. You will learn how to make someone look injured by photo manipulation. Enjoy.

Step 1:

Body Wounds

First open up an image of a part of a body with clean flesh that you want to give the effect to, I chose two people wrestling, and I zoomed in only on their arms.

Step 2:

Body Wounds

You are now going to want to select the Burn Tool (O). Set the brush to a size "5" soft (fuzzy) brush. Then in the drop down box (Range:) select "Highlights" and make the Exposure "15%". Do not select the airbrush.

Now start to draw a simple outline of where you want the wound to be. Remember, this is your "foundation" and you also want to try to follow the curves of the skin. Remember to leave some gaps of clean skin showing within the foundation. This will come in hand later.

Step 3:

Body Wounds

Switch to the dropdown box to "Midtones" now, and continue to draw around as you did above. This time, fill in the gaps of skin that was left over when making your "foundation". Then make a little outline around the foundation, but make it nice and smooth. This will give the wound some depth and a good effect as if the skin is cut, or torn.

Step 4:

Body Wounds

Switch to the dropdown box to "Shadows" now, and start to draw lines within the center. This will give a dry blood effect. The more times you go over your "Shadow" lines, the darker it gets, and the dryer the blood seems. Also add this effect to areas where you want more depth to show, hence "Shadows". As before make a little outline around the foundation, but make it nice and smooth. This will give the wound some depth and a good effect as if the skin is cut, or torn.

Step 5:

Body Wounds

start to add lines around the "foundation" with the "Shadows" selection, but make sure they follow the curves of the skin. You want these to look like some scratches.

Step 6:

Body Wounds

Continue to add more scratch lines and Shadowing detail. You may also resize the brush, and switch to "Midtones" and "Highlights". Also start to use the "Midtones" and "Highlights" around the edges of the "foundation" to make it look like the skin starts to rise a bit.

Step 7:

Body Wounds

Now select the Blur Tool (R). Use the Below Settings.

Start to blur the scratches (following the scratch line path) and a little bit of the inner wound.

Step 8:

Body Wounds

This is my final result. I decided to continue onto the rest of the arm, as well as the opponents arm. I did put more detail into the image, and added a little bit more of a blood ("Shadows") effect under each wound. It really just takes time and practice, but this is a taste of some photo manipulation, and what you can do in Photoshop. WARNING: This image may look realistic to you, so please be prepared.

Also, depending how well your image comes out, you can either keep it at it's current size, or you can make it smaller. To give it a better effect you can make the image a smaller size, because now there is more detail, and the image will not look that blurry. Here is an example:

Thank you, and I hope that you were able to get through this tutorial without having to turn away every few seconds/minutes. I also hope that you will apply this knowledge that you now have to other peices of art.
